The flowers are small, pink, and globular with a diameter of about 5-6mm, carrying up to 50 small stamens in the center.
Common names
Some of the common names of Mimosa diplotricha C.Wright ex Sauvalle include giant sensitive plant, catclaw, green wattle, chichicastle, and in the Philippines, it is called "makahiya" which means "touch me not" in Tagalog.
Uses
The leaves and stem of the Mimosa diplotricha plant have traditionally been used in herbal medicine for various ailments such as headaches, fever, and diarrhea. The plant is also used as fodder for livestock, providing much-needed nutrition. However, due to its invasive nature, the plant's use has mostly been discouraged.
Light Requirements
Mimosa diplotricha C.Wright ex Sauvalle, also known as giant sensitive plant, requires full sun to partial shade to grow optimally. It thrives in areas that receive a minimum of 6 to 8 hours of direct sunlight daily.
Temperature Requirements
The plant is known to grow well in tropical to sub-tropical regions where the average temperature ranges from 25 to 35°C. It is not frost-tolerant and cannot survive in areas with temperatures below 10°C. Once established, the plant can tolerate moderate droughts for short periods.
Soil Requirements
Mimosa diplotricha C.Wright ex Sauvalle prefers well-drained and fertile soils with a pH range of 5.0 to 6.5. It grows best in loamy soils enriched with organic matter. The plant can tolerate a wide range of soil types, including sandy, loamy, and clay soils. However, it cannot survive in waterlogged or poorly drained soils.
Cultivation of Mimosa diplotricha C.Wright ex Sauvalle
Mimosa diplotricha C.Wright ex Sauvalle, also known as Giant Sensitive Plant, is a tropical plant that requires warm temperatures to thrive. It grows up to 15 feet tall and 10 feet wide, forming a dense canopy of leaves.
The plant prefers full sun exposure and well-draining soils. It can tolerate a wide range of soil types, from sandy soils to clay soils. Before planting, enrich the soil with organic matter such as compost or aged manure to improve the soil structure and fertility.
Watering Needs for Mimosa diplotricha C.Wright ex Sauvalle
Mimosa diplotricha C.Wright ex Sauvalle requires consistent watering during its growing season. Water the plant deeply, allowing the water to penetrate the soil to the root zone. However, be careful not to overwater, as this can lead to root rot and other diseases.
During the dormant season, reduce the watering frequency to allow the soil to dry out slightly between waterings. Always check the soil moisture level before watering and adjust accordingly.
Fertilizing Mimosa diplotricha C.Wright ex Sauvalle
Mimosa diplotricha C.Wright ex Sauvalle appreciates regular applications of a balanced fertilizer during the growing season. Use a slow-release fertilizer to avoid the risk of burning the plant roots. Follow the manufacturer's recommendations on the label for the application rate and frequency.
Pruning Mimosa diplotricha C.Wright ex Sauvalle
Mimosa diplotricha C.Wright ex Sauvalle requires minimal pruning, mainly to remove dead or damaged branches. If the plant becomes too dense, you can thin out some of the branches to increase airflow and sunlight penetration. Prune the plant in late winter or early spring before new growth begins.
When pruning, use clean and sharp pruning tools to avoid tearing or damaging the plant tissues. Disinfect the pruning tools between cuts to prevent the spread of diseases.
Propagation of Mimosa diplotricha C.Wright ex Sauvalle
Mimosa diplotricha, also known as giant sensitive plant or Katong Tagalog, is a perennial shrub that belongs to the Fabaceae family. Its native range is tropical Central and South America. Propagation of this plant can be done through several methods, including seed propagation, stem cuttings, and layering.
Seed propagation
The seeds of Mimosa diplotricha can be collected when they are ripe and sown immediately in a well-draining potting mix. Germination usually takes around 7-14 days, and the seedlings can be transplanted into individual pots once they have several true leaves. It is important to keep the soil moist but not waterlogged during the germination period.
Stem cuttings
Stem cuttings can be taken from the plant during the growing season. Cuttings should be about 10-15 cm long and should be taken from the tips of the stems. Remove the lower leaves and dip the cut end in rooting hormone. Insert the cutting into a well-draining potting mix and keep it moist. Roots usually develop within 3-4 weeks, and the new plant can be transplanted into a larger pot or into the ground.
Layering
Layering is another method of propagating Mimosa diplotricha. This method involves bending a low-growing stem down to the ground and covering a portion of it with soil. The covered part of the stem will develop roots, and once these roots are well-established, the stem can be cut from the parent plant and transplanted into a new location. This method can take several months, but it has a high success rate.
Disease Management
Mimosa diplotricha C.Wright ex Sauvalle is susceptible to a variety of diseases, including fungal and bacterial infections. Some of the common diseases that can affect the plant include root rot, powdery mildew, leaf spot and stem cankers.
To manage these diseases, it is important to practice good sanitation measures in the garden or farm. This involves removing fallen leaves and debris from around the plant to reduce the chances of fungal infection. Additionally, it is important to avoid overwatering the plants and ensuring proper drainage to prevent root rot.
Fungicides and bactericides can also be used to manage diseases in Mimosa diplotricha. These should be applied according to the instructions on the product label, preferably early in the morning or late in the evening. This reduces the chances of the chemicals evaporating before they have a chance to be fully absorbed by the plant.
Pest Management
Mimosa diplotricha is also susceptible to pest attacks, including mealybugs, scales, spider mites, and aphids. Pests can cause significant damage to the plant, including stunted growth and discoloration of leaves.
To manage pest attacks, it is important to identify any infestation early and take appropriate measures. This can involve the use of insecticides or pesticides that are safe for the plant and the environment. It is important to only use the recommended amount of chemicals and to follow the instructions on the label.
Additionally, introducing predatory insects or beneficial nematodes can help to control pest populations. These insects can prey on pests and help to keep their populations in check, reducing the need for chemical control measures.
Regular monitoring of the plant can also help to identify any early signs of pest infestation. This can involve inspecting the leaves, stems, and flowers for any visible signs of damage or infestation.
Overall, effective disease and pest management in Mimosa diplotricha involves a combination of good sanitation practices, appropriate use of chemical control measures, and regular monitoring of the plant.
